Abstract
Section titled āAbstractāOptically active spins in solid state materials are an important candidate for quantum communication and distributed quantum computation over a network. To increase the size of quantum networks, long-lived quantum memories in a network node and high-fidelity control of qubits in the network nodes are desired. We discuss how isotopically engineered diamond can offer long-lived nuclear spin qubits that are robust to the optical link operation of the NV center. Furthermore, we use gate set tomography to report single-qubit and two-qubit gate fidelities exceeding 99.9% for the electron and nitrogen-nuclear spin of an NV center diamond.
